Rheu heart disease w rheumatoid arthritis of right hand

This code signifies a systemic autoimmune disorder characterized by chronic inflammation of the synovial joints, specifically affecting the right hand, and accompanied by cardiac manifestations due to rheumatoid disease. The heart involvement can include pericarditis, myocarditis, endocarditis, or valvular disease.

Apply this code when documentation clearly indicates a diagnosis of rheumatoid arthritis with specific involvement of the right hand joints, and there is co-occurring heart disease attributed directly to the rheumatoid process. This requires physician documentation explicitly linking the cardiac condition to the rheumatoid arthritis.

• Ensure the documentation specifies "rheumatoid heart disease" and not just a co-existing cardiac condition.
• Verify laterality for the hand involvement (right hand in this case).
• Sequence this code as a primary diagnosis if the rheumatoid heart disease is the main reason for the encounter, or as a secondary diagnosis if another condition is primary.
